The authors regret that there were some minor errors in the section “Material and methods” of our article. Therefore, I am writing this email on behalf of all authors, hoping to make corrections to the article. Here are the contents we want to correct:

  • 1.

    2.1 Preparation of daylily samples

Daylily samples were collected on July 2022 from four plant areas, including DT (113°32′ 27.75′′ N, 40° 05′ 24.32′′ E), LF (112°02′ 17.6′′ N, 36° 13′ 13.15′′ E), YQ (113°38′ 24.94′′ N, 37° 59′ 11.61′′ E) and LL (111°16′ 31.79′′ N, 37° 56′ 09.99′′ E) in Shanxi Province (Fig.1).

The representation of longitude and latitude is reversed, and the correct one is as follows:

“Daylily samples were collected on July 2022 from four plant areas, including DT (113°32′ 27.75′′ E, 40° 05′ 24.32′′ N), LF (112°02′ 17.6′′ E, 36° 13′ 13.15′′ N), YQ (113°38′ 24.94′′ E, 37° 59′ 11.61′′ N) and LL (111°16′ 31.79′′ E, 37° 56′ 09.99′′ N) in Shanxi Province (Fig.1).”

    2.4 The determination of total flavonoid content (TFC) and total polyphenol content (TPC)

TFCmg/g=V1×C1×D1/M1

V1- volume of the test solution (mL); C1- the concentration of flavonoid (mg/mL) in reaction solution obtained from the standard curve; D1- dilution ratio of polyphenol extraction solution; M1- sample mass (g).

It should be “D1-dilution ratio of flavonoid extraction solution”, rather than “D1-dilution ratio of polyphenol extraction solution”.

The authors would like to apologise for any inconvenience caused.
